GDD and this HEAT

So im just wondering what you guys are doing as far as the short window that GDD gives you for reapplication because of this heat!!!!
Those guys with 100 degree plus days are suggested to reapply every 7-9 days according to GDD calculations?
DO you still try to stay on a ruffly 14 day schedule? Or do you strictly follow reapplication at 200 GDD of T-nex.

@Spammage It will be interesting to collect clipping yield data for your weather. I'm not sure how far south the model was used, but I think it should still work.
@Spammage The greenkeeperapp is used on any web browser including phones.

This ppt slide explains the model in a lot of detail. Page 4 and 5 have how the clipping yields looks if applied every 4 weeks, 800 GDD, 400 GDD and 200 GDD. Look how it stays in suppression at 200GDD (top left page 6).

The best way to do this is to collect clipping data, but none of us want to do that too.
@Spammage Apply at the date. They already accounted for the 3-5 days for suppression.
